There isn't really much hint of that at the moment, although the spectre always lurks. I suppose China is a fairly strong example of how a 1-party state can achieve success.
Even then there is a pretty strong argument that their political organisation is one of the biggest things holding them back. The major strategic strength has been the program of encouraging and engaging with foreign investment and that doesn't require any particular political structure.
The first move in the Fascists playbook is destabilising and de-legitimising democracy. Suppression of dissent and centralising nationalist and unilateralist economic policies can only really come after the consolidation of centralised power.
Have we seen recent attempts to de-legitimise the democratic process in the US? Perhaps by someone willing to use state security forces to interfere in state policing of protests and escalate and provoke violence? Perhaps by a charismatic figure holding mass rallies in front of adoring worshipers of a cult of personality? Perhaps by someone encouraging militias and engaging in race baiting and nationalist unilateralism?
That's the playbook, but it starts with attacks on the democratic process. It's the key to everything else.
Evil clowns to the left, the Joker to the right, and I wish there was a middle to be stuck in.
You may go the "not a real scotsman" way here, but you don't even see a hint?

It's pretty fascinating stuff, though it can take a while to get through.
2,500 years is enough time to have passed that there aren't any inconvenient Helots still around to ask difficult questions.
